It is used for battery exchange such as portable game machine and thermometer. I purchased the battery cover screw because the precision screwdriver was the required size. There was a backlash in the color beads at the top of the driver and I was curious. It seems to be unsuitable for work that requires accuracy. It is used less frequently, I hope I can use it for the time being. I think that the price is also cheap for users who use it.
The feeling that you have in your hand better than what you have been using until now is easy to put in force when used. However, it is better to fix the round part of the plastic at the top without rotating and to have a shape that makes it easy to grip when turning the screwdriver.
